A study of various properties of silica fume concrete is reported. Var
ious properties of silica fume concrete, including slump, air-content,
compressive strength, flexural strength, permeability, and permeable
void volume, were investigated, and the effect of the silica fume repl
acement ratio of cement is described. The effects of aggregate content
and graduation, water-binder (cement + silica fume), and superplastic
izer dosage rate also are discussed. In this investigation, silica fum
e-binder ratios ranged from 0.00 to 0.40, water-binder ratios from 0.4
1 to 0.47, aggregate-binder ratios from 1.0 to 4.0, and superplasticiz
er-binder ratios from 0.01 to 0.05.
